CROSS-REFERENCE TO RELATED APPLICATIONS

This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 101208773 filed in Taiwan, R.O.C. on May 9, 2012, the entire contents of which are hereby incorporated by reference.

BACKGROUND

1. Technical Field

The disclosure relates to a ball-shape brawn training device and a ring thereof, and more particularly to a ball-shape brawn training device having a combined type ring and the ring.

2. Related Art

Conventional brawn training ball includes a casing, an outer ring, a rotatable ball, and a driving rope. The outer ring is disposed on the rotatable ball. The outer ring and the rotatable ball are installed in the casing. More particularly, the outer ring has flexibility so that the outer ring is capable of being deformed when manufacturing the training ball. Thus, when assembling the outer ring with the rotatable ball, the outer ring can be assembled to the rotatable ball by the deformation. Then, the outer ring and the rotatable ball are assembled into the casing. Next, the driving rope is twined on the surface of the rotatable ball. The rotatable ball begins to rotate with an initial rotate speed once the rope is polled out. In this way, a user can swing the brawn training ball to control the rotate speed.

Recently, in order to meet consumers' demand, manufacturers have strived to improve the brawn training ball to have more additional functions. For example, in the Taiwan patent application M391415 (herein after referred to as NO. 415 application), the brawn training ball has an elastic structure. In this case, a user holds the brawn training ball and rubs the surface of the brawn training ball on a surface of an object so that the ball rotates to increase the elastic potential energy of the elastic structure. Furthermore, the training ball is activated and therefore rotates due to the restoring force of the elastic structure while the brawn training ball leaves the surface of an object. Thus, it is not necessary to use the driving rope to make the rotatable ball of the brawn training ball rotate.

Furthermore, in the US patent application U.S. Pat. No. 7,846,066B1 (herein after referred to as No. 066 application), the brawn training ball has a light emitting device. The light emitting device includes an electricity energy generating circuit and a light emitting control circuit. The electricity energy generating circuit can generate electricity by the rotation of the brawn training ball, and the electricity generated is outputted to the light emitting control circuit. Besides, the light emitting control circuit can present different light emitting effects according to different rotate speed of the ball.

According to NO. 415 application and No. 066 application, the brawn training ball is equipped with only one additional element. The deformation needed by assembling the outer ring and the rotatable ball is still in the range of the largest mounting deformation quantity which is retained previously for the outer ring. However, in order to better satisfy consumers, the brawn training ball trends to have more additional functions. Therefore, if the brawn training ball is equipped with more than one additional elements, the deformation needed by assembling the outer ring and the rotatable ball may be beyond the largest mounting deformation quantity which is retained previously for the outer ring and thus the outer ring cannot be assembled to the rotatable ball by the outer ring's deformation. In this case, when the brawn training ball needs to have various additional functions, manufacturers need to develop other methods for assembling the outer ring and the rotatable ball. Otherwise, additional elements with additional functions are hard to be equipped to the brawn training ball due to assembly problems.

According to the embodiment of FIG. 1A, the ball-shape brawn training device comprises a casing 100, a ring 200, and a ball body 300. The casing 100 may be made of transparent plastic and has two parts of upper casing 110 and the lower casing 120. The upper casing 110 is detachable to the lower casing 120. The upper casing 110 has an opening 111.

The ring 200 is configured in the casing 100 and is rotatable relative to the casing 100. With reference to FIG. 3B, the ring 200 comprises a first pivot part 211 and a second pivot part 230 opposite to each other, and a first ring section 213 and a second ring section 214. The first ring section 213 connects one end of the first pivot part 211 and one end of the second pivot part 230. On the other hand, the second ring section 214 connects the other end of the first pivot part 211 and the other end of the second pivot part 230.

It should be noted that, the ring 200 of the embodiment substantially is composed of a ring body 210 and an assembly 220, as shown in FIG. 3B. Besides the first pivot part 211, the first ring section 213, and the second ring section 214, the ring body 210 further comprises a first assembly portion 212. The first pivot part 211 and the first assembly portion 212 are disposed at two opposite sides of the ring body 210. The first ring section 213 connects one end of the first pivot part 211 and one end of the first assembly portion 212, and the second ring section 214 connects the other end of the first pivot part 211 and the other end of the first assembly portion 212. Furthermore, the assembly 220 comprises a second assembly portion 221. The second assembly portion 221 can be combined with the first assembly portion 212 so that the assembly 220 and the first assembly portion 212 form the second pivot part 230.

More particularly, the first assembly portion 212 has two arms 218. The second assembly portion 221 has two grooves 223. The two arms 218 can be detachably assembled into the two grooves 223. It may be understood that the number of the arms 218 and the number of the grooves 223 are not intended to limit the disclosure. In addition, the structures of the first assembly portion 212 and the second assembly portion 221 are not limited by this embodiment. For example, the structure of the first assembly portion 212 can be interchangeable with that of the second assembly portion 221.

In addition, with reference to FIGS. 3A and 3B, the first ring section 213 has a first protrude edge 215 on its outer surface and the second ring section 214 has a second protrude edge 216 on its outer surface. The second assembly portion 221 has a third protrude edge 222 on its one side. As a result, the first protrude edge 215, the second protrude edge 216, and the third protrude edge 222 form a ring protrude edge 240, as shown in FIG. 3A. The ring protrude edge 240 is configured in the casing 100 and is rotatable relative to the casing 100.

In this embodiment, the first pivot part 211 comprises a first carrying portion 217 which is disposed at the side of the first pivot part 211 close to the first assembly portion 212. The assembly 220 further comprises a second carrying portion 225. The second carrying portion 225 and the third protrude edge 222 are disposed on the two opposite sides of the second assembly portion 221. Furthermore, the second carrying portion 225 is disposed at the side of the second assembly portion 221 close to the first pivot part 211.

In this embodiment, the first pivot part 211 has a hole 219. The second pivot part 230 has a hole 224. More particularly, the hole 224 is disposed on the assembly 220 and goes through the second assembly portion 221, the third protrude edge 222, and the second carrying portion 225.

As shown in FIG. 2, the ball body 300 is coupled to the first pivot part 211 and the second pivot part 230 and is rotatable relative to the ring 200. The ball body 300 further comprises a first spindle 320 and a second spindle 330 opposite to each other. The first spindle 320 and the second spindle 330 goes through the holes 219 and 224 respectively so that ball body 300 can rotate relative to the ring 200.

In this embodiment or other embodiments, the ball body 300 has a friction portion 310 on its surface. A part of the friction portion 310 protrudes from the casing 100 through the opening 111. As a result, users may use hand or surface of desk to contact with the friction portion 310 and thus rotate the ball body 300.

In this embodiment or other embodiments, with reference to FIGS. 1A and 2, the ball-shape brawn training device 10 further comprises a magnetoelectricity conversion element 400. The magnetoelectricity conversion element 400 comprises a magnet 410 and a sensing circuit 420. The magnet 410 is disposed on the second carrying portion 225 of the assembly 220. The sensing circuit 420 is disposed in the ball body close to the second spindle 330. The magnet 410 and the sensing circuit 420 are between the ball body 300 and the assembly. When the ball body 300 rotates relative to the ring 200, the sensing circuit 420 will rotate relative to the magnet 410 so as to generate a magnetoelectricity effect.

Furthermore, the ball-shape brawn training device 10 further comprises a light source 500 which is electrically connected to the sensing circuit 420. The sensing circuit 420 generates electricity by the magnetoelectricity effect, and then the light source 500 can emit light. The light source 500 rotates with the ball body 300 and the light emitted from the light source forms a beautiful light track. In this case, the visual effect of the ball-shape brawn training device 10 can be enhanced. The light source 500 can be for example a diode-emitting diode.

In this embodiment and other embodiments, with reference to FIGS. 4A and 4B, the ball-shape brawn training device 10 further comprises an elastic structure 600. One end of the elastic structure 600 is fixed to the first carrying portion 217 of the first pivot part 211, and the other end of the elastic structure 600 is fixed to the ball body 300. A user may rotate the ball body 300 by rubbing the friction portion 310 so that the ball body 300 rotates relative to the ring 200. When the ball body 300 rotates relative to the ring 200, the elastic structure 600 will store the kinetic energy for the rotation of the ball body 300. The kinetic energy stored by the elastic structure may drive the ball body 300 to rotate until the user releases the ball body 300.

Because the magnetoelectricity conversion element 400 and the elastic structure 600 are disposed on the ring 200 of the ball-shape brawn training device 10, the ring 200 cannot be detached from or assembled to the ball body 300 only by the elastic deformation.

With reference to FIGS. 4A and 4B, FIGS. 4A and 4B are schematic diagrams of ring 200 before and after the elastic deformation. In this embodiment, the first carrying portion 217 of the first pivot part 211 is equipped with the elastic structure 600 and the second carrying portion 225 of the second pivot part 230 is equipped with the magnet 410. Thus, the depth of the hole 219 and the depth of the hole 224 are deeper when the first and second pivot parts are equipped with objects than that when they are not equipped with object. In this case, the ring 200 needs larger deformation so as to make the holes 224 get off the first spindle 320 and the second spindle 330.

However, as shown in FIG. 4B, when a user applies a force F, the second pivot part 230 moves far away from the first pivot part 211. At this time point, the first ring section 213 and the second ring section 214 are pulled to get close to each other by the force F. The second pivot part 230 has the largest displacement quantity when the first ring section 213 and the second ring section 214 abut on the ball body 300. However, the displacement at this time is not big enough to separate the second pivot part 230 from the second spindle 330. Therefore, when the first pivot part 211 and the second pivot part 230 are equipped with additional elements, the ball-shape brawn training device 10 can be quickly assembled by the combined type ring 200 of this embodiment.

With reference to FIGS. 5A-5D, FIGS. 5A-5D show the assembly flow of the ball-shape brawn training device 10 of FIG. 1A.

Firstly, as shown in FIG. 5A, the ring body 210 of the ring 200 and the assembly 220 are not assembled to the ball body 300. Secondly, as shown in FIG. 5B, the assembly 220 is assembled to the second spindle 330 and the second spindle 330 goes through the hole 224 along the arrow direction a. Then, as shown in FIG. 5C, the hole 219 of the ring body 210 is assembled to the first spindle 320, and the two arms 218 of the first assembly portion 212 are assembled to the two grooves 223 of the second assembly portion 221 along the arrow direction b. As a result, the ring is assembled to the ball body 300. It is noted that the order for assembling the ring body 210 and the assembly 220 to the ball body 300 according to this embodiment is not used to limit the disclosure.

According to the ball-shape brawn training device and the ring as described above, the ring has two parts of a ring body and an assembly. The first pivot part of the ring body and the second pivot part of the assembly are firstly assembled to the two spindles of the ball body, and then the assembly is combined with the ring body to form a whole ring. As a result, when the two pivot parts of the ring are equipped with additional elements, the ring can be quickly assembled to the ball body.

In addition, because the ring of the disclosure has two parts for the assembly, the ball-shape brawn training device can be equipped with more additional elements in a limited space. Thus, the ball-shape brawn training device may have more additional functions.
